[QUOTE="barefooter56, post: 1127537, member: 85389"] coastbuck, Ok. Lets just start over instead of jumping around and getting aggravated. I would suggest you drop back to the lowest powder charge listed for either the RETUMBO or H4831 SC and redo the seating depth testing. Lets find/confirm that again and then work your load back up in half grain increments until you get to two grains below maximum then drop the tenth grain increments checking for pressure signs and accuracy as you go up in charge. The seating depth accuracy node usually only occurs once. The velocity accuracy node may repeat as you go up in charge. It usually starts either with a "large" or "small" group and then closes or opens up as the charge is increased then starts to repeat the process. Think of the group on the targets as a "sine" wave on an oscilloscope . The rifle will tell you how high you can go in velocity. Its work , but it pays off in the end. Keep a good loading log book and only change ONE thing at a time. Hope this helps! [/QUOTE]
